A wedge is a triangular shaped tool which is an inclined
plane. It is one of the six simple machines. It can be
used to separate two objects or portions of an object,
lift an object, or hold an object in place. A wedge looks
like two inclined planes stuck together. The edge of a
wedge is often called the blade.
WEDGE
One difference between a wedge and an
inclined plane is that, while the inclined
plane stays still, a wedge moves to do its
work. To chop down a tree, someone must
swing the axe. To cut out a paper heart,
you need to move the scissor blades up
and down.
